Our XRF expert Matt Kreiner looks at why people are getting ...

  • Impact of Corrosion on Electronic Equipment

    Corrosion is the destruction of metals through reaction with compounds in their environment. It is a natural process because compounds such as oxides, sulphides and chlorides are formed and these are stabler than pure metals. Electronic circuits and components are omnipresent in our environment. Until recently, the thousands of soldered joints that an electronic circuit contains were ...

  • Corrosion of Electronic Components by Hydrogen Fluoride

    Generation of hydrogen fluoride (HF) from fire suppression by some gaseous agents is a major concern, because HF causes corrosion. Without proper precautions, the HF corrosion damage to some electronic facilities can be significant. A study has been carried out to evaluate the corrosion effect of HF on electronic equipment. This article describes details of the corrosion study in terms of test ...

  • On the Ground with Diesel Corrosion - Case Study

    When the EPA revealed the results of its study in July on the increasing presence of substantial corrosion in diesel fuel tanks, it proved that the problem is much larger than anyone anticipated. The facts are staggering: 83%of the diesel tank systems exhibited moderate-to-severe corrosion. 75%of the owner/operators of those diesel tanks had no idea it was ...

  • Wear and corrosion preventative solutions to increase power plant efficiency

    For many years energy demand has been strongly growing and will continue. The installation of new plant capacity can take years so there is an enormous pressure on power plants to improve operational output, efficiency and availability. Component repair rather than replacement produces immediate costs savings and also reduces the use of materials, energy and transport in ...

  • How UV can reduce corrosion in swimming pool structure - Case Study

    In 1985, twelve people were killed in Uster, Switzerland when the concrete roof of a swimming pool collapsed after only thirteen years of use.  The roof was supported by stainless steel rods in tension, which failed.  The Federal Materials Testing Institute, based in Duebendorf, Switzerland, and the Federal Materials Research and Testing Institute of Berlin concluded that the collapse ...

  • Reasons and prevention of corrosion-induced failures of prestressing steel in concrete

    Serious damages in post- and pretensioned prestressed components have occurred due to hydrogen-induced stress corrosion cracking of prestressing steel. The failures happened due to onsite conditions and were favoured by the sensitivity of the steels towards hydrogen. The contribution describes the mechanism of the fracturing process, the corrosion testing of prestressing steel and gives an ...

  • Case histories of using tin technology to control corrosion in water systems

    Stannous chloride is an alternative corrosion control in aqueous systems. Stannous chloride’s effectiveness as a better corrosion inhibitor has been demonstrated in both municipal drinking water and industrial cooling water applications and its use has a reduced impact on rivers and streams. Orthophosphate and other phosphate compounds are the most common treatments for reducing corrosion in ...

  • Combating Corrosion - Committee G01 Standards Fight Nature’s Destructive Tendencies

    The evening news may leave many of us feeling war-weary, but one ASTM International technical committee has been successful in conflict of a different sort. It’s a commonplace but epic struggle between the natural and civilized worlds — the fight against metal corrosion. For the past half-century, the weapon of choice of ASTM Committee ...

  • EPA Study: 83% of diesel tanks have moderate to severe levels of corrosion

    The EPA has released the results of the largest survey to-date on corrosion levels in underground storage tanks (USTs) containing diesel fuel -- and the results are staggering. The research showed that 83 percent of the USTs studied exhibit moderate to severe corrosion. Worse, only 25 percent of the owners of those tanks with corrosion were aware of it prior to the study. ...

  • Effect of electrochemical treatment at fresh condition in enhancing the corrosion resistance in concrete

    The present study concerns the electrochemical treatment to increase the resistance against chloride–induced corrosion of steel in concrete, which was ensured by a microscopic examination and corrosion tests. The current density (DC) applied to the embedded steel immediately after casting of concrete ranged 125, 250 and 500 mA/m² for two weeks. As a result, an increase in the current ...

  • Failure analysis showing the effect of sulphur content in stainless steel on the resistance to stress corrosion cracking in marine environments at ambient temperatures

    The risk of environmentally assisted cracking in downhole components is high due to sour conditions, i.e. the presence of hydrogen sulphide. Therefore a range of materials possessing excellent corrosion resistance are employed. However, corrosion is not only downhole related but is also a common problem on the platform deck itself due to airborne salts from ocean spray. For this reason the ...
